APPARATUS FOR ATTAGHING FILLETING TO THE FLAT-BARS OF CARDING-ENG-INES.

Application filed February 6, 1911.

To all whom it may concern:

Be it known that I, JAMES DRoNsrrELD, a subject of the King of Great Britain and Ireland, residing at the Atlas Works, Oldham, in the county of Lancaster, England, card-grindingmachine maker, have invented new and useful Improvements in Apparatus for Clothing or Attaching Filleting to the Flat-Bars of Garding-Engines, of which the following is a specification.

This invention relates to an apparatus for mounting card filleting (such as is provided with sheet metal fasteners) upon fiat bars, which form the chain of flats used in revolving flat cards.

The improved machine is of a class adapted to work on flat bars designed to take a sheet metal fastener which is rolled down upon the flat bar.

The drawings attached illustrate my apparatus for the indicated purpose.

In said drawings :Figure 1 is an end view of the apparatus. Fig. 2 shows a further end view, partly in section. Fig. 3 is a longitudinal side view and illustrates halves of the complete carriage in two positions. Fig. 4 is a plan. Fig. 5 shows a de tail view of a flat bar clamping bracket, &c. Fig. 6 shows a modified and preferred form of flat bar clamping bracket. Fig. 7 indicates a flat bar and foundation with one known form of sheet metal clip attached.

In apparatus according to this invention I utilize a main bed a, capable of ready attachment to a bench or table. This main bed a, has a fixed longitudinal jaw b and a movable longitudinal jaw 12. The movable jaw b is guided, with respect to the other, by

studs 19 which pass through slots 6 and are screwed into the main bed, and, is adjusted, by transverse set screws 0 having suitable heads 0. Said longitudinal jaws b b are shaped to seat and grip the fiat bar A (see Figs. 1, 2 and 5) and to form as it were a longitudinal vise into which the length of filleting and flat bar can be introduced. To insure that the filleting and flat bar are properly bedded together, V-shaped clamps such as cl, shown in Fig. 5, may be used, the bent or shaped extremities d of which hook below or onto trunnions d or studs attached to the longitudinal jaws. Such clamps have a screw-adjusted block 6, with recess 6, which bears on the rib of the flat bar A, as seen in Fig. 5. As a modification, the limbs cl of the clamps may be piv- Specification of Letters Patent.

oted, at (lg, to a part d which carries the screw adjusted block c with recess e, the limbs in this case being independent and pivoted. Small, spring actuated, plungers 7, press outward the upper extremities of the limbs (Z of such clamp. The modified clamp is not liable to fracture, because the pivoted parts can better accommodate themselves.

one to another. The hooked extremities (Z are shown engaging below projections 12* formed in one with the halves of the longitudinal vise. WVhatever form of clamp be used, the function is to hold down the flat and foundation while the transverse set screws 0 are adjusted, after which, the clamps are removed.

Mounted on the main bed, is a carriage, made up of two traveling brackets g, g, which run on antifriction rollers, there being small rollers h h on the top, and long rollers i 2' below, the rollers below having inner collars z", 2", and turning on clamped sleeves 2' Through each two sleeves i 2' (which are in alinement), a spindle is passed, having a head or collar 7" at one end, the rear half of the complete carriage, however, being movable laterally on the spindle j when adjusted along with themovable half of the bed I) or longitudinal vise. Immediately below the jaws of the longitudinal vise b, b, and intermediate of the sleeves 2' 2' for the long rollers i, 2', is a bracket is held at two points by the transverse spindles j, and, to this bracket, is attached the ends of a pitch chain Z. This pitch chain Z passes over toothed pinions m, m mounted one at each end of the machine, one of said pinions being driven by a hand-lever m or hand wheel. Movement of the chain Z traverses the carriage g, g, which is guided by the bars I), Z) and runs on the anti-friction rollers h, c, that is, four rollers back and front. Each half of the traveling carriage g, g is formed with, or has attached, quadrantbrackets g, 9, having quadrant guide ways g g to accommodate correspondingly shaped quadrant projections 9 g on a main bracket 9 which can be moved angularly through an are equal to 45, or thereabout. Each main bracketg carries an adjustable set screw 9 andhandleg, together with a pawl and spring plunger 9 to act on the pawl 9 The main bracket g can assume two positions, one at 45 tothe other, and, the pawl 9 looks the bracket 9* in either position by engaging with notches cut in the quadrant shaped projections g on the carriage halves.

Fitting in cut grooves in each main bracket is an auxiliary bracket 9, which has attached to it a bearer or support g which carries a rolling down bowl set at 4-5 to the vertical, the attachment being made flexible for preference, say, by the use of a screwed bolt 72 and spring a, to allow yielding of the bearer and bowl 0 in the event of any obstruction being encountered. A screwed stud may if desired be passed through the auxiliary bracket and caused to bear on the bowl bearer or support to allow of adjustment of the bowl 0. The auxiliary bracket and consequently the rolling down bowl 0, on each side, can be advanced and retracted by the set screw The operation of clothing a fiat bar, is, as follows. I place the flat bar A face downward, with the foundation B below the face, and carrying the clips on the edges. The movable jaw Z) of the longitudinal vise is then set-up to the requisite degree, and the pressing down clamps (Z or (Z are applied and adjusted. Next, the longitudinal vise is screwed up tight. The operator then actuates the set-screws 9 g to advance the auxiliary brackets 9 9 and force the bowls 0 properly against the sheet metal clips, said bowls 0 0, as stated, being disposed to roll down the clips to the extent of degrees. This done, the lever handle m is turned and the carriage g, g traversed along the bed,and over the clips, to perform one half of the rolling down process. After this, the main brackets g g are simply turned-up 4L5", and the pawls g snap into the notches the turning-up of said brackets moving the bowls 0, 0 into a vertical position and pressing down the clips just at the point of contact. This accomplished, the hand lever m is again turned, and the carriage g, g is traversed from end to end, over the bed, and, the rolling down bowls 0 0 press the clips down level on the flat back and secure a proper attachment. By the use of the applied set screws g acting on the bowl carriers T can arrange to adjust the position of the bowls 0, 0 somewhat, apart from the movement due to the turning-up of the main bracket. After a proper rolling down, the main brackets 9*, g* are turned back to the horizontal again, the auxiliary brackets are screwed back, and the vise released, whereupon the properly clothed bar can be removed and a fresh one inserted.

The machine works easily, and is very simple, and compact.

Obviously variations in construction can be made while retaining the main features.

I declare that what I claim is.
